windows修改mysql字符集，支持ios emoji标签

windows为my.ini或者my-default.ini（linux配置文件my.cnf，在/etc目录）

找到后请在以下三部分里添加如下内容：

[client]

default-character-set = utf8mb4

[mysql]

default-character-set = utf8mb4

[mysqld]

character-set-client-handshake = FALSE

character-set-server = utf8mb4

collation-server = utf8mb4_unicode_ci

init_connect='SET NAMES utf8mb4'

重启服务，查询一下

show global variables like '%char%';

是不是如下造型



关键的来了，修改相应表字段，支持emoji：

alter TABLE topic_video_comment modify `comment` VARCHAR(500) CHARACTER set utf8mb4 COLLATE utf8mb4_unicode_ci null COMMENT '回复内容';

OK，perfect

下面虽然能改变当前的字符集，但是好像没作用…………暂时也展示出来吧！

SHOW VARIABLES WHERE Variable_name LIKE 'character%' OR Variable_name LIKE 'collation%';

set character_set_client = 'utf8mb4';

set character_set_connection = 'utf8mb4';

set character_set_database = 'utf8mb4';

set character_set_results = 'utf8mb4';

set character_set_server = 'utf8mb4';

set collation_connection = 'utf8mb4_unicode_ci';

set collation_database = 'utf8mb4_unicode_ci';

set collation_server = 'utf8mb4_unicode_ci';
